• A. A-(i),B-(ii),C-(iv),D-(iii)
• B. A-(ii),B-(iii),C-(iv),D-(i)
• C. A-(iv),B-(iii),C-(ii),D-(i)
• D. A-(iv),B-(ii),C-(i),D-(iii)

Answer 1

The correct option is C A-(iv),B-(iii),C-(ii),D-(i)

Meiosis has the prophase stage which is the longest phase of karyokinesis otherwise. It is then divided into five different phases. Leptotene is the phase where the chromosomes are present as a long thread with chromomeres on it. Zygotene is the second stage where the pairing of synopsis of homologous chromosomes takes place here. In the stage. Pachytene is the stage where crossing over or exchange of segments between non-sister chromatids of homologous chromosomes takes place. Diplotene is the stage where the chromosome begins to separate and terminalization starts. Diakinesis is the stage where the nuclear membrane starts degeneration. Metaphase is the stage where the chromosomes arrange themselves on the metaphase plate. Anaphase is the place where he the separation of the chromosomes takes lace and disjunction takes place.

Thus, the correct answer is 'A-(iv), B-(iii), C-(ii), D-(i).'
